Specification of Letters Patent.

Patented Feb. 17 191 1.

Application filed May 19, 1913. Serial No. 768,403.

To all whom it may concern Be it known that I, \VALTER S. Boron, a

citizen of the United States, residing at Sarmay be extended any direction,

atoga Springs, in the county of Saratoga and State of New York, have invented an Improvement in Tree-Sprayers, of which the following is a specification.

'Heretofore, various devices have been designed for spraying trees, but so far as I am aware, in the use of none of these has it been possible to so spray the leaves of a tree as to reach all the parts of the same without climbing into the tree, and the object of my present invention is the construction and provision of an apparatus by which, from the ground or road-way, it is possible to so spray the tree as to reach both the inner and outer sides of all the leaves so that the same may be properly treated.

In carrying out my invention,

I preferably employ a truck, upon which is mounted a plurality of telescoping pistons, which so as to reach the desired height. These pistons are preferably revolubly mounted longitudinally so as to be turned to any position about their axis, and adapted to be tilted to any required angle, and secured to the outer or free end of the outermost telescoping piston, I employ a revoluble device, to which a nozzle is secured, together with means for turning the revoluble device so as to turn the nozzle in making it possible, as will be hereinafter more particularly described, to so set the telescoping pistons and nozzle as to reach all the parts of a tree, with any desired spraying liquid.

In the drawing, Figurel is a front elevation of my improved tree sprayer. Fig. 2 is a side elevation of the same. Fig. 3 is an enlarged longitudinal cross section illustrating the manner in which the telescoping pistons are connected, Fig. 1 is a transverse cross section of a collar on which the telescoping pistons are revolubly mounted. Fig. 5 is a cross section of the revoluble member and associated parts to which the nozzle is connected. Fig. 6 is a sectional plan of a spraying nozzle, and Fig. 7 is a plan of the weights employed with a handle secured to the lowermost member of the telescoping pistons. Figs. 1 to 7, inclusive,

also being shown on enlarged scales for the clearness of illustration.

Referring to the drawing, 10 indicates a truck provided with wheels 11, and if desired, intermediate springs, upon which my improved tree sprayer is preferably supported so as to be readily moved from one place to another. This truck, it will be understood, will be provided with a suitable pole 12, by which itmay be drawn. Fixed on the truck are series of standards or inclined supports 13, fixed to the upper ends of which is a head 14. Suitably secured on the head 14, I may employ a lug 15, and pivotally connected, as indicated at 17 on the lug 1 1, is a divided collar indicated at 16. The inner surface of this collar is preferably provided with one or more race-ways 18. I also employ a plurality of telescop ing pistons indicated at 19, 25, 26 and 27. The lowermost piston 19 is provided with flanges 19, on the surface of which are also provided race-ways similar to the race-ways 18 in the collar 16. The divided collar 16 of the piston 19 is received between the flanges 19 and secured therein by means of bolts 20 or otherwise, a seriesof balls 21 being employed in the race-ways between these parts to form bearings therefor, so that the piston 19 may be readily turned within the collar 16.

Adjacent to the lower end of the piston 19, the same may be provided with handles 22, to which may be secured one or more weights 23 employed to balance the apparatus when the same is tilted from a vertical position on the pivotal point 17 as will be readily understood. Each of these weights 23 is provided with a set screw 2d,-

by means of which it may be clamped to position on the handle 22.

' Each of the telescoping pistons fits and is movable within the next adjacent piston, and as illustrated in Fig. 3, the joint between the pistons is preferably made by employing a cap 28, fixed to the upper end of one piston. This cap 28 is provided with a cylindrical portion 29 of approximately the same interior diameter as the exterior diameter of the next adjacent piston, and through which the lower end of this next adjacent piston passes and is adapted to slide. On the lower end of this next adjacent piston is a collar 30, adapted to engage the cylindrical portion 29 of the cap 28, and between the collar and the end of the cylindrical portion 29, I employ a suitable packing ring 31, in order to make a tight joint between these parts. In the lower end of each of the next adjacent pis tons I may employ a member designated as 82, provided with suitable apertures, in which are revolubly mounted rollers indicated at 33, these rollers being so placed that they are adapted to contact with the inner surface of the piston.

Secured to the piston 1.9, and preferably at its upper end, is an inlet connection 34, to which a supply pipe 35 is connected. This supply pipe leads to a pump or other suitable mechanism by which the fluid under pressure may be supplied to the interior of the pistons to force the same apart to any desired extent, it being understood that the pistons may be forced apartby admitting the fluid under pressure and are brought together by shutting off the supply and withdrawing the fluid under pressure- Suitably fixed on the outer or free end of the uppermost piston 27 is a bifurcated head 36. Revolubly mounted in this bifurcated head is a pipe 37. Fixed to the pipe 37 between the bifurcated portions of the head 36, is a roller 38 around which a rope 39 or other similar device passes in order that by the roller 38 the pipe 37 may be revolved. Suitably swiveled, as indicated at 4:1, to one end of the pipe 37 is an elbow 40, to which is also connected a pipe 42 for supplying the liquid to be used in spraying a tree, the liquid being forced from a suitable source of supply through the pipe 42 by any suitable means. 7 Fixed on the opposite end of the pipe A7 is a head 43, extending from which is an arm AA adapted to carry a weight 45, employed to balance the parts when fixed in any desired position. Extending from the head 43, in a position diametrically opposite to the arm 44, is a pipe arm A6, at the end of which a nozzle 47 is secured. This nozzle 4-7 may be provided with a series of spraying tips 48, as indicated, or the liquid with which the tree is to be treated may escape from the nozzle through any other suitable means without departing from the nature of my invention.

As will be understood from the foregoing description, the telescoping pistons may be extended to any desired length, within their limit of extension, which is suflicient to reach the top of the highest tree. These telescoping pistons may be turned to any position about their axis within the collar 16, and may also be tilted to any desired angle about the pivotal point 17. Furthermore, the nozzle may be so turned to any desired position as to reach not only the under side but also the outer side of the leaves of a tree by turning the revoluble pipe 37 through the roller 38 so as to set the nozzle in the required position to accomplish this purpose.
